PHP5实例:简简单单生成条形码
本文中使用的是PHP5的版本。在使用前注意要将PHP的GD模块开启。在Windows中为php_gd2.dll,Linux中为gd.so。将压缩文件解压到Apache,执行。PHP5生成条形码见下图:
1. Type:选择条形码类型
2. Output:输出的图片格式
3. Thickness:条形码高度
4. Resolution:条形码大小
5. Font:条形码下方的文字大小,也可不显示文字

$code->setScale(2); // Resolution $code->setThickness(30); // Thickness
$code->setForegroundColor($color_black); // Color of bars $code->setBackgroundColor($color_white); // Color of spaces

1 - Filename (empty : display on screen) 2 - Background color */
$drawing = new BCGDrawing('', $color_white); $drawing->setBarcode($code);
$drawing->draw(); // Header that says it is an image (remove it if you save the barcode to a file)
header('Content-Type: image/png'); // Draw (or save) the image into PNG format.
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
